Title: Detection of ultrasonic signals from disturbed liquid interfaces or surfaces
IPC: G01F23/00
Filed: 1981-06-15
Abstract: Reflected ultrasonic signals from liquid interfaces or surfaces may vary widely in amplitude if the interface or surface is disturbed by, for example, agitation. The detection problem posed by this wide dynamic range of reflected signals is overcome by amplifying each reflected signal to such an extent that the relevant noise level is always a significant proportion of the associated detection threshold. In general, if the threshold detection level is constant then the amplifier gain must vary in a controlled manner during the period within which a specific reflected signal might be received. This procedure ensures that the greatest possible proportion of individual reflected signals are recognized whilst maintaining freedom from spurious responses. <IMAGE>

Title: Weighing machine with built-in calibrating means
IPC: G01G23/01
Filed: 1981-10-15
Abstract: A weighing machine, operable on the principle of electromagnetic force compensation, comprises a weighing pan (3) for reception of a load to be weighed, a coil (11) through which a current flows and arranged in the field of a permanent magnet system (10) for the production of a counterforce balancing the load, a built-in, calibrating weight (18) which can be lowered, as shown, to load the weighing system, and an electronic evaluating system (26-28) providing an indication of the weighing result. The calibrating weight (18) does not need to be adjusted to a particular weight during manufacture since a storage element (17), in which the weight value of the calibrating weight (18) is digitally stored, is included in the electronic evaluating system. Calibration at some time after manufacture is carried out by lowering the calibrating weight and comparing the then measured value with the previously stored value. The calibration load can be applied via a lever, Fig. 3 (not shown). <IMAGE>

Title: Self monitoring solid state switching system
Inventor: FISHER KENNETH WALTER JAMES
IPC: G08B29/04
Filed: 1981-10-16
Abstract: A solid state switching system for use with solenoid operated control valves, a self checking monitor system and a logic interface, has a plurality of switching elements arranged in such a way that no single electrical fault can result in an inadvertent energisation of the control valve. The monitor system verifies that no fault has occurred during any one cycle of operation which might not otherwise be apparent e.g. failure of one switching element to revert to its open circuit state. Every component in the switching and monitoring circuits functions during each ON/OFF cycle. The logic interface will only permit a subsequent cycle to commence when every monitor output from each switching system is satisfactory. This invention is particularly applicable to an interface between the control valves for dangerous machinery and a light screen guard fitted for personnel protection. <IMAGE>

Patent GB-2119187-A (GB)
Title: Telecommunication exchange protection
Inventor: BISHOP ANTHONY PETER
IPC: H02H9/04
Filed: 1982-04-16
Abstract: Telephone line circuit protection is made somewhat difficult with electronics in the line circuit since the electronic devices may blow more quickly than the fuses. To avoid this each line wire is connected to a threshold detection device (X1, X2), which responds when its line wire voltage is out of specification. Such a response is used to fire thyristors or triacs (TR1, TR2) to ground both the line wires and thus to blow one or both of the fuses (F1 or F2). To ensure that a permitted out of specification voltage, such as ringing does not erroneously cause fuse blowing further detection devices (X3-X6) are connected across the line wires and in series with one line wire. These detect whether the voltage comes from the exchange side, in which case it is OK, or from the line side, in which case it is wrong. If it is OK a logic unit LU, via which the thyristors or triacs are fired, is blocked. Thus the fuses are only blown in response to a genuine fault. <IMAGE>
